SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 452,776, dated May 26,1891..

Application filed December 1, 1890. Serial No. 378,603- (No model.)

To aZZ whom it may concern.-

Be it known that I, WALLACE W. Dory, a citizen of the United States,residing at Pneblo, in the county of Pueblo and State of Colorado, haveinvented a new and useful Sash-Lock, of which the following is aspecification.

The invention relates to improvements in adjustable combined sash-locksand anti'sash rattlers.

The object of the present invent-ion is to provide a simple andinexpensive sash-look capable of enabling the sashes of a window to bereadily adjusted and secured at anydesired position, either open orclosed, and adapted to prevent the sashes rattling.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a window provided witha saslrlock and anti-rattler embodying the invention. Fig. 3 is ahorizontal sectional view. Fig. 1 is a detail perspective view of thecasing and bolt, the casing being partially broken away. Figs. 5, 6, and7 are detail views.

Referring to the accompanying drawings, 1 and 2 designate the upper andlower sashes of a window, the former of which is provided withsocket-plates 3 and 3, arranged to be engaged by a sliding bolt 4,mounted in a casing 5, secured to the upper meeting-bar 6 of the lowersash 2. Theinner engaging end of the bolt 4: is provided with anelongated T-shaped head '7, which has its outer end oppositely beveledor pointed, and the said head 7 is adapted to engage a groove 8 of thesocket-plate 3, and after such engagement to be turned transversely ofthe groove. The plates 3 are provided with a circular opening or socket9, having at its bottom the horizontal groove 0r slot 8, and the saidsockets or openings 9 are arranged at suitable intervals.

In the upper windows of a house where a sash-lock is unnecessary and itis only desirable to secure the windows at certain points of adjustment,plates 3 are employed and are provided with a continuous groove or slot8, which does not necessitate disengagement of the bolt from the plateduring the adjustment of the sashes, and the said plates 3 and 3 areseated in suitable recesses. The bolt 4 is mounted in a rectangularcasing 5, constrneted of metal and having its inner and "inner and outersides 10 and 11 by screws or other suitable means, which will enable thesaid parts to be readily removed when access 'to the interior of thecasing is desired, and

the bottom 15 is constructed of two sections secured to the meeting-bar6 by screws and provided at their end with flanges 16 and 17, the latterof which is arranged at a slight angle to the side 12 to conform to theinclination of the adjacent face of the meeting-bar 6, and the said topis provided with a knob 18 to prevent the casing coming in contact withthe window-frame when the lower sash is raised to the full extent. Thebolt4= is provided intermediate its ends with an annular flange 19,having a pin 20 projecting from its periphery, and arranged upon thebolt between the said flange 19 and the inner side 10 of the casing is aspiral spring 21, which normally holds the bolt out of engagement withthe socket-plate, and when the bolt is engaged with the socket-plates itretains the shoulders 22 of the head 7 in oppositely-disposed notches23, arranged at the inner face of the socket-plate on each side of thegroove or slot 8. The pin 20 of the annular flange 19 is adapted toengage a guide-rod 24 and a stoprod 25, both of which are arrangedWithin the casing 5 parallel with the bolt and enable the latter to bereadily controlled. The guiderod 24: is arranged at one side of thebolt, and is adapted to be engaged by the pin 20 to hold the elongatedhead 7 horizontally and in proper position to enterthe slot or groove 8of the plate 3. Then the .bolt is pushed against the action of thespiral spring 21,and after the head has entered the slot or opening 8the bolt is turned to the right until the pin 20 is brought intoengagement with the stoprod 25, when the head 7 will be at right anglesto its position on entering the socket and will be transversely of theslot or groove 8. The outer portion 26 of the bolt is threaded and isengaged by a thumb-nut 27, adapted to be adjusted along the bolt tolimit the reach of the same, and to be screwed against the casing whenthe bolt is locked to prevent the bolt becoming disengaged from a socketof the plate 3, and the casing is provided with an annular flange 28,arranged around the opening 12 in the outer side 11 to prevent thethumb-nut coming in actual contact with the said side. When the bolt islocked and the shoulders 22 of the head 7 are in engagement with therecesses 23 of the socket-plate, if the thumb-nut 27 be screwed againstthe flange 28 it is impossibleto disengage the bolt. It will thus beseen that the sash-lock is capable of securely fastening the sashes andpreventing the samebein g separated without breaking their frames. Thesashes can be adjusted for the purpose of ventilation and can be lockedin such positioin, and when so locked are rigidly held together and canbe moved together in the window-frame. Then the bolt is locked and thethumb-nut is not against the flange 28 of the casing, the spiral springwill prevent the sashes rattling. The

outer end of the bolt 4 is provided with a knob 29,having integralpoints or projections 30 arranged at diametrically-opposite points andextending in the direction of the pin 20, thereby indicating theposition of the pin and facilitating the operation of the bolt. The head7 of the bolt is oppositely beveled or pointed to direct the bolt into asocket of the plate 3 should the bolt strike the edge of a socket, andthe vertical edges of the inner side 10 of the casing 5 are beveled andthe face of the side is the same width as the socket-plate, whichconstruction facilitates the adjustment of the sash-lock and enables theparts to be readily applied to a window.

The sash-lock may be applied, as illustrated in the accompanyingdrawings, to the stiles of the sashes; but it may be used equally aswell on the center muntins, and I desire it to be understood that I donot limit myself to the precise details of construction herein shown anddescribed, as I may, Without departingfrom the spirit of the invention,make minor changes therein.

It will readily be seen that the combined sash-lock and anti-rattler issimple and inexpensive in construction and capable of enabling thesashes to be adjusted as desired, and of securely lockingthem whenadjusted, and that rattling and shaking of the sashes is prevented.

To assist the operator in determining when the point of the bolt isopposite a socket, the socket-plate is provided in its outer face with aseries of horizontal grooves 31, which are arranged above the sockets adistance equal to the distance the point of the bolt is from the upperedge of the case, whereby when the upper edge of the case is broughtopposite one of the grooves the "point of the bolt will be opposite asocket.

Having thus described my invention, what I claim is- 1. In a sash-lockand anti-rattler, the combination of the socket-plate having the slot 8and provided with notches arranged on opposite sides of the slot, thecasing, the sliding bolt arranged in the casing and provided at one endwith a beveled head 7, having shoulders 22 adapted to engage saidnotches, said bolt having the threaded portion 26, and the nut arrangedon the threaded portion of the bolt, substantially as described.

2. The combination, in a sash-look and anti-sash rattler, of thesocket-plate, the easing, the bolt sliding in the casing and provided atone end with the head 7 and having near the opposite end the threadedportion 26, and provided intermediate its ends with an annular flangeand having a pin projecting from the flange, the guide and stop rodsarranged within the casing and adapted to be engaged by-said pin,thethumb-nut arranged on the threaded portion of the bolt,

and the knob secured to the outer end of' the bolt and havingprojections extending in the direction of said pin, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
